WebOct 12, 2024 · If heat is removed from a substance, such as in freezing and condensation, then the process is exothermic. In this instance, heat is decreasing the speed of the molecules causing them move slower (examples: liquid to solid; gas to liquid). These changes release heat to the surroundings. WebFeb 15, 2024 · The energy released upon freezing is a latent heat, and is known as the enthalpy of fusion and is exactly the same as the energy required to melt the same amount of the solid. Is energy added when freezing? When water freezes it gives up some of the water’s energy. This energy that is given up is the latent heat of freezing.
